Civil Partnership: Any Difference When One of You Dies?

Yes. In almost every respect that matters when one of you dies, a civil partnership gives a surviving partner the same protection as a marriage. The two are treated alike under the intestacy rules, the inheritance tax exemption for transfers between partners applies to a civil partner in exactly the same way, and forming a civil partnership revokes an earlier will just as a wedding does. If you registered a civil partnership rather than marrying, the person you registered it with is your legal next of kin for these purposes, with the same standing a husband or wife would have.

This still surprises people, usually because civil partnership is talked about as if it were a lesser or provisional version of marriage. In law it is not. Since the Civil Partnership Act 2004 came into force at the end of 2005, Parliament has deliberately mirrored the death-and-money consequences of marriage across to civil partnership, and where later reforms changed the rules for one they changed them for the other. The differences that remain are narrow, mostly historical, and worth knowing precisely so you are not relying on a half-remembered worry at the worst possible time.

Below is the comparison item by item, across intestacy, inheritance tax, pensions and wills, with the few places where the answer is not quite identical flagged as they come up, including one that depends on which part of the UK you live in.

The short answer: near-identical, with a few footnotes

The purpose of civil partnership was to give couples the legal consequences of marriage under a different name, and when the death consequences were written they were copied across rather than reinvented. So the safest starting assumption is that anything true for a married couple on death is also true for civil partners. That assumption holds for the three questions people actually ask: who inherits, whether there is a tax bill, and what a pension pays a survivor.

Where you need to be careful is not the substance but the wording. Some statutes reach the same result through a separate section written specifically for civil partnership, and a small number of older pension scheme rules were drafted before civil partnership existed and had to be corrected afterwards. Those corrections are why the footnotes exist. None of them changes the headline: a surviving civil partner is protected as a surviving spouse is.

It is worth separating civil partnership firmly from simply living together, because the two are often muddled. A couple who live together, however long and however committed, have none of this. If that describes you, the position is completely different and is set out in our guide to being engaged and living together, the months with no rights. Registering the partnership is the act that switches the protections on.

Intestacy: a surviving civil partner inherits as a spouse would

If someone dies without a valid will, the intestacy rules decide who inherits, and they name a surviving civil partner in the same breath as a surviving spouse. The partner takes the deceased's personal possessions, then a fixed statutory legacy set in law, and then a share of the rest, with the remainder going to any children. Where there are no children, the surviving partner generally takes the whole estate. This is precisely the treatment a married survivor receives; there is no reduced version for civil partners.

That protection is real, but relying on intestacy rather than a will is still a poor plan, and not only because the fixed legacy can be smaller than a partner needs. Intestacy is rigid: it cannot leave a particular item to a particular person, it cannot provide for a stepchild you never adopted, and it decides nothing about who raises your children. A civil partnership gives your partner a place in the queue. A will controls what they actually receive and how quickly.

Contrast this with a couple who are unmarried and not in a civil partnership. There, the intestacy rules do not mention the partner at all, whatever the length of the relationship, and the estate passes to blood relatives instead. The gap is at its most painful over tax, which is the next section, and we have set it out in full for unmarried partners facing inheritance tax with no exemption.

Inheritance tax: the exemption applies in full

This is the difference that costs real money, and here civil partners are treated identically to spouses. Anything one partner leaves to the other is exempt from inheritance tax, without limit. It does not matter whether they leave a modest sum or an entire estate worth several times any threshold; a transfer between civil partners on death carries no inheritance tax.

The nil-rate band, the amount an estate can pass before inheritance tax is charged at all, is £325,000, and anything above it that is not otherwise exempt is taxed at 40%. Because transfers between partners are exempt, a civil partner can leave everything to the survivor with no tax, and any part of the nil-rate band left unused transfers to the survivor's own estate to use later. The same transferable allowance applies to the additional residence nil-rate band where a home passes to direct descendants.

None of this is available to a couple who merely live together. An unmarried survivor inheriting a home worth more than the nil-rate band can face a tax bill measured in tens of thousands of pounds on a house they already lived in, precisely because there is no partner exemption to shelter it. That single difference is why couples in long unmarried relationships sometimes register a civil partnership for the protection alone, and it is the clearest illustration that the label is doing legal work, not just describing a feeling.

Pensions and death in service: where a little history intrudes

For most pension arrangements the answer is again the same. State Pension survivor rules treat a civil partner as a spouse. Public sector schemes pay a survivor's pension to a civil partner. A defined contribution pension pot can be nominated to a civil partner exactly as to a husband or wife, and an employer's death in service lump sum can name them on the expression of wish form.

The footnote lives in older occupational schemes. Because civil partnership did not exist before December 2005, some scheme rules originally counted only service from that date when working out a survivor's pension for a same-sex partner, which could sharply reduce what a long-serving member's partner received. A Supreme Court decision in 2017 held that this was unlawful discrimination, so a same-sex partner's survivor pension must now be worked out on the same pensionable service as an opposite-sex spouse's would be. If your partner is in an older defined benefit scheme, it is still worth asking the administrators in writing what a survivor would be paid, so nothing is built on a rule that should already have been corrected.

One thing that catches people out has nothing to do with civil partnership at all: an employer's death in service benefit is usually paid at the discretion of the scheme trustees, not automatically to whoever is named. That discretion matters most after a relationship ends, which is why we have set out separately how trustees decide a death in service benefit after a divorce. Keep any nomination current, because a stale form pointing at a former partner is the commonest reason the money goes somewhere you did not intend.

Your will, and what dissolution changes

In England, Wales and Northern Ireland, forming a civil partnership automatically revokes any will you made beforehand, unless that will was expressly written in expectation of the partnership with that named person. This mirrors the rule for marriage, and it catches couples who tidily made wills while planning the partnership only to have the ceremony cancel them, dropping the estate back into the intestacy rules. If you are registering a civil partnership, treat a new or confirmed will as part of the paperwork, not an afterthought.

Dissolution works the same way as divorce. A will is not revoked by dissolution, but from the date of the final order any gift to the former partner, and their appointment as an executor, take effect as if that person had died first. The rest of the will stands. The trap is a will that leaves everything to a former partner and names no substitute: strip the former partner out and the estate can fall to be shared under the will's fallback provisions or, if there are none, under intestacy, which may hand it to relatives you would not have chosen. Reviewing the will the moment a dissolution is finalised is the fix.

Second relationships add their own complication where a home and children from an earlier relationship are involved, because providing for a new partner and preserving something for the children pull in opposite directions. That balancing act is the subject of our guide to a second marriage, one house and children from the first, and the same tensions apply to a civil partnership formed later in life.

Where a policy still earns its place

Legal protection settles who is entitled to what. It does not create money that was not there, and it does not always arrive quickly. A surviving civil partner may inherit the house and still be unable to afford the mortgage on one income; the estate may be exempt from tax and still be tied up for months before anything can be released. Life cover is what turns an entitlement into cash your partner can use in the weeks after a death rather than the year after.

A policy written in trust for your partner sidesteps the estate altogether. It pays out directly to them, without waiting for probate and outside the intestacy calculation, which is useful even where your partner would inherit anyway. Where there are children who depend on your income, the amount needs to reflect the years that dependency will run, and it is worth reading how to size that properly rather than guessing at a round number, which we cover in costing a childhood you would not be there for. If you want to see what cover against your own circumstances would look like, you can get life insurance quotes and have an FCA-authorised broker price it against your actual mortgage, income and family.

Scotland and Northern Ireland

The headline protections hold across the whole UK. Inheritance tax is a UK-wide tax, so the partner exemption and the nil-rate band work identically in Scotland and Northern Ireland, and both recognise civil partnership as marriage's equivalent on death.

The wills point is where Scotland genuinely differs. In Scotland, neither marriage nor forming a civil partnership revokes an existing will, so a will made before the partnership stays in force rather than being cancelled by it, which is the opposite of the position in England, Wales and Northern Ireland. Scotland also gives a surviving partner and any children fixed protected entitlements, known as prior rights and legal rights, that apply regardless of what a will says, and these can override an attempt to leave a partner or child out. We explain how those claims work, and why they matter most in blended families, in our guide to Scotland, where your children can claim against your estate. Northern Ireland follows the broad England and Wales pattern under its own succession legislation, including revocation of a will on forming a civil partnership.

Frequently asked questions

Do civil partners have the same inheritance rights as spouses?

Yes, in substance. The intestacy rules treat a surviving civil partner exactly as they treat a surviving spouse, the inheritance tax exemption for transfers between partners applies in the same way, and forming a civil partnership revokes an existing will in England, Wales and Northern Ireland just as marriage does. The protections were deliberately written to mirror those of marriage.

Are pension survivor benefits the same?

For most schemes, yes. State Pension inheritance and public sector scheme rules apply to civil partners as they do to spouses. Some older private scheme rules once counted less service when working out a survivor's pension for a same-sex partner, a limit the courts have since struck down, so it is worth asking your scheme in writing what your partner would actually receive.

Does dissolving a civil partnership change our wills?

Dissolution does not revoke a will, but from the final order any gift to a former civil partner, and their appointment as executor, take effect as if they had died first. The rest of the will stands, which can produce an outcome you never intended if no substitute was named. Reviewing the will as soon as the dissolution is final is the safeguard.
